Title: Martin Mars [4.12] [update 2021 03 12]
Post by: Lone Wolf on December 12, 2019, 11:04:00 PM
The Martin JRM Mars is a large, four-engined cargo transport seaplane designed and built by the Martin Company for the United States Navy during World War II. It was the largest Allied flying boat to enter production, although only seven were built. The United States Navy contracted the development of the XPB2M-1 Mars in 1938 as a long range ocean patrol flying boat, which later entered production as the JRM Mars long range transport.

Four of the surviving aircraft were later converted for civilian use to firefighting water bombers. One example of the aircraft still remains based at Sproat Lake just outside of Port Alberni, British Columbia, although it is not operational.


Update 2021 03 12 : Martin Mars v2.1


v2.1 with the improvements as they came in BAT v4.1.2

Improved FM by vampire_pilot
cockpit udate by vampire_pilot
water clips corrected by vampire_pilot

New FM by vampire_pilot
Loadouts cleaned, turret code and options removed, bombs removed, as Mars was a transport only
Firebomber option for Civilian Mars

Firebomber loadout and effects developed by mace!
Taken from his great TCat mod.


This is the FSX Martin Mars model by Peter Hall and I take no credit in it's creation. I merely ported it into IL-2 1946 basing it on the Short Sunderland available here https://www.sas1946.com/main/index.php/topic,50850.0.html. This also uses the cockpit of the Sunderland which is accredited to all those in the link above. Thanks to all.

Note that this uses six .tga's for the skins. I would never have gotten this kind of detail on one .tga.

** The planes are not skinnable! **

Tested only on B.A.T 3.7.2 so far.

I remember watching these back in the late 90's on a TV show called "The Air Show"... Hawaii Mars and Philippine Mars flying as fire bombers... Philippine Mars is now in a museum after being painted up in US Navy deep blue... THANKYOU!!  ;D ^-^

Bringing this vehicle is really awesome, thanks!

However, either I am missing something or the only difference between the two slots is the default skin?
If that's so, for a BAT integration, I'd use only one slot then.

scratch that, I saw there's different antenna arrays!

Also, if I read correctly, the Mars was to be a transport only, bombing equipment omitted in the prototype already. I'd also remove the bombing loadout accordingly. There's also a lot of remnants in the java about onboard gunner ammunition selection, which is not present anyway.

I've been flying the plane as AI in a few missions. One point seems to be that the FM makes it very manoeuvrable. The plane can twist and turn and swerve along with the best fighter planes when being shot at. I would have thought it to be a bit more lumbering.

I don't know how to adjust an FM or link another existing FM to the plane or i would do some tweaking myself. Does anyone else notice the same?

... well, that's why they only built 7, because the Mars was a too tough adversary for fighters ...!  :D

More seriously, Kermit tells you all about the Mars, here :




... and here, Kermit flies the Hawaii water bomber ...!

unfortunately, this bird cannot be skinned in a normal fashion due to way the 3d is structured, I am afraid.

Thanks for all your kind words and compliments.

 I wish I could take credit for this but that rightly belongs to Peter Hall and the Sunderland team.

If you do a search on Google there are some civilian skins available for this.

Does anybody know what's necessary to make a bomber drop bombs in a train by default? (one single key command to drop all load in a train)
Is this some java code?

Because If I knew how to set this up, I could make the civilian Mars a waterbomber. We have a "water bomb" available.
Right now I only get "bombs" to drop one at a time, one a t a key command....

Just create a new Weapon "BombGunXXXX" Class with the line:
Property.set(class1, "cassette", 1);

It's a trick that exists in Russian and Italian charges with small bomblets!

Thanks a lot for your upgrade, Lone Wolf !  ;D

.. I am currently being expelled to the OUTSIDE VIEW of civil with firefighting loadout.
This happens within 4 seconds in the pit, and repeats within the first five minutes of game.  ::(

I posted a v2.1 with the last enhancements as I made them for BAT 4.1.2

The FM should be much less bouncy in the water. The FM is also reworked, along with cosmetic changes to the cockpit (you can now sit in the left seat!)

A belated thank you for this update.  I was just thinking about this flying boat after watching this:


And then noticed this update.  Thank you again.
